Nancy Chu Woo received her BFA from Cornell University in 1963, and her MA from Columbia University in 1964. She returned to Hong Kong in 1973, and for a number of years she taught in the Department of Fine Arts at the University of Hong Kong, The Chinese University of Hong Kong and the Hong Kong Arts Centre.
She studied Western painting in the United States. After finishing her training, she stayed on to teach and spent a total of fourteen years in New York. During this time, she established a strong foundation in various genres of Western art. Before she left for the United States, as well as after her return to Hong Kong, she studied under Zhao Shao'ang and Yang Shanshen, both great masters of the Lingnan school. As a result, Woo absorbed the essense and skills of traditional Chinese calligraphy and painting as well. It was through Yang that Woo was inspired to explore and develop her own unique style of splashed ink landscape painting, in which she mixes ink with gouache colours to create brilliant, semi-abstract compositions, as well as incorporates themes such as the human figure.
Woo has exhibited all over the globe, including Belgium, Germany, Thailand, Singapore, Japan, Canada, and across the US, with important solo exhibitions at the Guangzhou Museum of Art and the Shanghai Art Museum in China, the Parliament House in Ottawa, Canada, and the University Museum and Art Gallery at the University of Hong Kong.
Her works have been collected by the Hong Kong Museum of Art, the Hong Kong Heritage Museum, the University of Hong Kong, and the Guangzhou Museum of Art.
